When creating a post, the community is only validated if you enter the name and click it

Describe the bug
When creating a new post, you have to enter the display name of the community and click it from the list. If you enter the canonical community name (e.g. [email protected]) it will not validate and you cannot post. The toast message says that a community must be selected.

To Reproduce (if applicable)
Steps to reproduce the behavior:

1. Click Create -> Post
2. Type in the canonical name of the community you want to post in (e.g. [email protected])
3. Fill in the rest of the post details
4. Try to submit
5. Yellow warning toast pops up in corner saying "You need to set a community"

Expected behavior
The form should recognize that a valid community has been provided.

Versions

• Browser: Chromium / Firefox
• Photon version: 0.8.4

Also, creating a new post from the community page (/c/community@tld) sometimes does not behave consistently/correctly.

Steps to reproduce (again, this is inconsistent, so it may take a few tries):

1. Click a community from the sidebar
2. From the navbar, click Create -> New Post
3. Check the "Community" field in the /create/post form that is rendered.

There are three different behaviors I've observed:

1. The community is correct and validated (has the green check). This is the expected behavior and occurs most of the time.
2. Sometimes it's the wrong community entirely (typically one you've browsed earlier).
3. The community is pre-filled correctly, but there is no green check and submitting the post warns you that "You need to set a community".
